Ordered several of these from the same seller when they were £5.83 but obviously didn't last too long at that price. Still hot at £6.52, hopefully they'll keep it at this price for longer. http://www.hotukdeals.com/deals/sandisk-8gb-microsd-hc-memory-card-5-83-amazon-indigostarfish/869554
Though the description still says Class 2 rating, everyone that replied back on my previous post of this deal confirmed they received Class 4's as shown in the red retail packaging under the main pic.
